Table 8 — Desktop Evaluation of Federally -Listed Plant Occurrence (cont.) Scientific Name Common Name Likelihood of Onsite Federal State Typical Habitat/Substrate/ Known Distribution in Justification for Onsite Likelihood Reference Occurrence Status Ranking Elevation Colorado Determination Alpine tundra in calcareous peat Mosquito Range in Park and Known populations are not in regional Eutrema fens in limestone or dolomite. Summit Counties proximity to project site. No appropriate Penland alpine fen http://www.centerforplantconservation.org/collecti edwardsii ssp. No likelihood T S1/S2 Elev. 12,300-13,100 ft. habitat or substrate exists on the project mustard on/cpc_viewprofile.asp?CPCNum=1921 penlandii site.

"Wetland A" of wetland delineation report (Barr 2009) may be suitable, but likely too small to support a population.

Species is highly endemic to one area in one County. Pediocactus Knowlton cactus No likelihood E n/a Gravelly soils formed from tertiary Archuleta County Not known to occur in the region. Onsite http://www.fs.fed.us/database/feis/plants/cactus/p know/tonii alluvial deposits within sparcely- substrate is unsuitable. Extreme rarity edkno/all.html vegetated areas in pinyon -juniper makes the species unlikely to be found woodlands and sagebrush onsite shrublands. Elev. 6800-6900 ft. Penstemon Parachute Very Unlikely T S1 Steep slopes of Green River Roan Plateau in Garfield Known populations are within regional http://nativeecosystems.org/species/plants/parach debilis beardtongue Formation shale within arid, County proximity (nearby county); habitat is ute-penstemon sparsely vegetated habitat. Elev. somewhat appropriate in places. 7900-9200 ft. Elevational range of project site is outside of species range. Onsite presence is unlikely due to rarity and endemism.
